The maintenance of pure primary lymphocytes culture for long periods may be difficult because of its inability to divide continuously. In addition, lymphocytes separation methods such as Ficoll-Paque, RBC lysis and immunomagnetic microbeads separation may have some affect on cell viability. The objective of this study is to determine various types of lymphocytes purification methods, in order to prolong primary lymphocytes culture to 72 hours. The second objective is to use these primary lymphocytes as targets for quantitative and qualitative cell viability assays when analysing the action of toxins isolated from natural products. Human blood was drawn and purified by using Ficoll-Paque, RBC lysis or
immunomagnetic separation column method in various combinations. The purified lymphocytes were also grown with and without the growth enhancement factor, concanavalin-A. Cell viability assays were carried out for 72 hours at 24 hours interval. The lymphocytes purified using RBC lysis method, with or without concanavalin-A can prolong 100% cell viability for 72 hours whilst lymphocytes purified using Ficoll-Paque and supplemented with concanavalin-A showed an increase in cell viability of over 250% at 72 hours incubation. It was observed only lymphocytes purified using Ficoll-Paque followed by the immunomagnetic microbeads separation method and supplemented with concanavalin-A showed overall cell viability increase, reaching 300% at 72 hours incubation. This method was a reliable model to test the cytotoxicity of the Bacillus thuringiensis parasporal inclusion, suggesting that the method achieves the objectives of the study.

Medical Education research is a relatively
new field but one that is progressing rapidly worldwide.
This article is an attempt to take stock of the current
status of Medical Education research in International
Medical University and to explore the various factors
that have influenced its direction. It also shares some of
the initiatives that have been instituted or intended to
be instituted at our university.

PURPOSE: Problem-based learning (PBL) is usually conducted in small-group learning sessions with approximately eight students per facilitator. In this study, we implemented a modified version of PBL involving collaborative groups in an undergraduate chiropractic program and assessed its pedagogical effectiveness. METHODS: This study was conducted at the International Medical University, Kuala Lumpur, Malaysia, and involved the 2012 chiropractic student cohort. Six PBL cases were provided to chiropractic students, consisting of three PBL cases for which learning resources were provided and another three PBL cases for which learning resources were not provided. Group discussions were not continuously supervised, since only one facilitator was present. The students' perceptions of PBL in collaborative groups were assessed with a questionnaire that was divided into three domains: motivation, cognitive skills, and perceived pressure to work. RESULTS: Thirty of the 31 students (97%) participated in the study. PBL in collaborative groups was significantly associated with positive responses regarding students' motivation, cognitive skills, and perceived pressure to work (P<0.05). The students felt that PBL with learning resources increased motivation and cognitive skills (P<0.001). CONCLUSION: The new PBL implementation described in this study does not require additional instructors or any additional funding. When implemented in a classroom setting, it has pedagogical benefits equivalent to those of small-group sessions. Our findings also suggest that students rely significantly on available learning resources.

Purpose:
The impact of the coronavirus disease 2019 crisis on medical education includes reduced clinical training, a significant loss of learning time and a probable decline in confidence of being a doctor. These recent changes will have significant effect on the well-being of medical students and interventional support needs to be given early. This study explores the challenges faced and coping strategies used by preclinical medical students during the crisis.
Methods:
A qualitative study involving 13 preclinical medical students was conducted between August and September 2020 at a medical school in Malaysia. An in-depth individual interview via Microsoft Teams (Microsoft Corp.) with semi-structured questions was conducted. The recorded interview data were thematically analyzed using the six phases of Braun and Clarke’s Thematic Analysis.
Results:
The challenges faced were identified under three themes: psychosocial impact of lockdown, significant lifestyle changes, and impact on professional progression. Meanwhile, four themes emerged in coping strategies that include behavioral strategies, re-appraisal of the uncertainties of situation, active coping mechanisms, and regulation of emotion with coping reserve. There are indications that personality traits determine strategies to cope with challenges faced during the crisis which may either lead to resilience building or experiencing burnout.
Conclusion
The findings of the study highlighted the urgent need to develop early preventive and intervention strategies to address the mental health of medical students to mitigate stress and promote positive well-being in times of crisis.

Purpose:
Direct student involvement in quality processes in education has been suggested to encourage shared responsibilities among faculty and students. The objectives of this study were to explore undergraduate health professions students’ understanding of quality assurance (QA) in education, and identify the challenges and enablers for student involvement in an Asian context.
Methods:
Twenty semi-structured interviews were conducted among medical, dentistry, and pharmacy students in a Malaysian University. The interviews were audio-recorded, transcribed verbatim, and thematically analyzed to understand the students’ perspectives of QA in education.
Results:
The participants recognized the importance of QA towards ensuring the quality of their training, which will consequently impact their work readiness, employability, and quality of healthcare services. Academic governance, curriculum structure, content and delivery, faculty and student quality, teaching facilities, and learning resources were indicated as the QA areas. The challenges for students’ involvement included students’ attitude, maturity, and cultural barrier. To enhance their buy-in, clear objectives and impact, efficient QA mechanism, and recognition of students’ contribution had been suggested.
Conclusion
The findings of this study support student-faculty partnership in QA processes and decision making.

Purpose:
The perception of faculty members about an individually tailored, flexible-length, outcomes-based curriculum for undergraduate medical students was studied. Their opinion about the advantages, disadvantages, and challenges was also noted. This study was done to help educational institutions identify academic and social support and resources required to ensure that graduate competencies are not compromised by a flexible education pathway.
Methods:
The study was done at the International Medical University, Malaysia, and the University of Lahore, Pakistan. Semi-structured interviews were conducted from 1st August 2021 to 17th March 2022. Demographic information was noted. Themes were identified, and a summary of the information under each theme was created.
Results:
A total of 24 (14 from Malaysia and 10 from Pakistan) faculty participated. Most agreed that undergraduate medical students can progress (at a differential rate) if they attain the required competencies. Among the major advantages mentioned were that students may graduate faster, learn at a pace comfortable to them, and develop an individualized learning pathway. Several logistical challenges must be overcome. Providing assessments on demand will be difficult. Significant regulatory hurdles were anticipated. Artificial intelligence (AI) can play an important role in creating an individualized learning pathway and supporting time-independent progression. The course may be (slightly) cheaper than a traditional one.
Conclusion
This study provides a foundation to further develop and strengthen flexible-length competency-based medical education modules. Further studies are required among educators at other medical schools and in other countries. Online learning and AI will play an important role.
